Description

Technical Field

[0001] This utility model relates to the field of water electrolysis cell technology, and in particular to an auxiliary device for assembling a water electrolysis cell. Background Technology

[0002] Depending on the type of electrolyte, hydrogen production through water electrolysis can be categorized into alkaline water electrolysis and proton exchange membrane (PEM) water electrolysis. The electrolyzer structures of these different technologies are similar, consisting of a sandwich structure made of multiple layers of sheet components. The main components include end plates, current collectors, electrode plates, electrodes, and an electrolyte membrane, all secured by screws around the perimeter. Precise alignment of the stacked sheet components is crucial to prevent displacement due to tightening forces during the assembly process.

[0003] Traditional assembly methods rely on manual visual identification of sheet components and their stacking on a workbench. This approach is not only inefficient and lacks precision, but also inconvenient due to the solid metal nature of the electrolyzers, making movement and maneuvering difficult, time-consuming, and labor-intensive. Furthermore, there is a risk of the electrolyzers falling and causing injury. While existing technologies offer many mature mounting bases, they are generally specialized and unsuitable for water electrolyzer assembly. Therefore, this application proposes an auxiliary device for assembling water electrolyzers to address these issues. Utility Model Content

[0004] Based on this, in order to solve the problems existing in the prior art, this application provides an auxiliary device for assembling a water electrolysis cell, including a base;

[0005] The tray has its bottom surface rotatably connected to the base via a rotating component.

[0006] At least two positioning rods are arranged vertically at circumferential intervals on the top surface of the support tray;

[0007] A pad is placed at the center of the top surface of the pallet.

[0008] Furthermore, the rotating assembly includes a load-bearing column and a turntable. One end of the load-bearing column is fixedly connected to the support tray, and the other end is fixedly connected to the turntable. The turntable is fixedly installed on the base, and the turntable, the load-bearing column, and the support tray are arranged coaxially.

[0009] Furthermore, there are two positioning rods, symmetrically arranged on both sides of the pad.

[0010] Furthermore, the positioning rod can slide along the radius of the pallet.

[0011] Furthermore, the positioning rod includes a rod body and a slider. The support plate is provided with an elongated hole, the length direction of which is consistent with the radius direction of the support plate. A groove is provided on the side of the support plate away from the pad and below the elongated hole. The slider is slidably disposed in the groove. The rod body passes through the elongated hole and is connected to the slider.

[0012] Furthermore, the diameter of the base is larger than the diameter of the support tray.

[0013] Beneficial effects: This application can quickly position the sheet components of the electrolytic cell by setting the positioning rod, which improves the assembly accuracy and assembly efficiency. At the same time, the support tray is set to be rotatable, which facilitates the installation of bolts at different positions of the electrolytic cell. Rotating the support tray also helps to check the alignment accuracy of each component during the assembly of the electrolytic cell sheet. Attached Figure Description

[0023] like Figure 1-2 As shown in the figure, this application embodiment provides an auxiliary device for assembling a water electrolysis cell, including: a base 1;

[0024] The bottom surface of the tray 2 is rotatably connected to the base 1 via a rotating component;

[0025] At least two positioning rods 5 are vertically arranged at circumferential intervals on the top surface of the support tray 2;

[0026] Pad 6 is located at the center of the top surface of the support tray 2.

[0027] In this embodiment, the cross-sections of the base 1, the support tray 2, and the positioning rod 5 are all circular. The diameter of the base 1 is larger than the diameter of the support tray 2. This makes the auxiliary device more stable during the assembly of the electrolytic cell 7, less prone to tipping over, improves assembly efficiency, and reduces safety risks.

[0028] There are two positioning rods 5, which are symmetrically arranged on both sides of the pad block 6;

[0029] The pad 6 is fixed on the support tray 2. During the assembly of the electrolytic cell 7, the electrolytic cell 7 is placed on the pad 6 so that there is a certain gap between the electrolytic cell 7 and the support tray 2. The gap is greater than the thickness of the nut. The area of ​​the upper end of the pad 6 is slightly smaller than that of the electrolytic cell 7. This design exposes the nut area at the edge of the electrolytic cell 7, leaving enough space for tightening the nut with a wrench.

[0030] The sheet components of the electrolytic cell 7 are provided with positioning holes that are identical in number, shape and size to the positioning rods 5. The positioning rods 5 can pass through the positioning holes on the electrolytic cell 7 to position the sheet components of the electrolytic cell 7.

[0031] In use, first, the positioning rod 5 passes through the sheet components of the electrolytic cell 7 in sequence. At this time, the positioning rod 5 can quickly position the sheet components and limit the sheet components of the electrolytic cell 7, so that the sheet components of the electrolytic cell 7 are stacked on the pad 6 in sequence. Then, the support tray 2 is rotated to tighten the bolts at different positions of the electrolytic cell 7. At the same time, rotating the support tray 2 helps to check the alignment accuracy of each component during the assembly of the electrolytic cell 7 sheet components. After the assembly is completed, the assembled electrolytic cell 7 can be pulled out from the positioning rod 5.

[0032] This application uses a positioning rod 5 to quickly position the sheet components of the electrolytic cell 7, improving assembly accuracy and efficiency. At the same time, the support tray 2 is designed to be rotatable, which facilitates the installation of bolts at different positions of the electrolytic cell 7. Rotating the support tray 2 also helps to check the alignment accuracy of each component during the assembly of the electrolytic cell 7 sheet.

[0033] In one embodiment, the rotating assembly includes a load-bearing column 3 and a turntable 4. One end of the load-bearing column 3 is fixedly connected to the support tray 2, and the other end is fixedly connected to the turntable 4. The turntable 4 is fixedly installed on the base 1, and the turntable 4, the load-bearing column 3, and the support tray 2 are arranged coaxially.

[0034] In this embodiment, the tray 4 consists of a fixed bottom cover and a rotatable top cover, with a ring of steel balls or nylon balls sandwiched in the middle. The tray 2 is installed on the base 1 by the load-bearing column 3 and the turntable 4. The load-bearing column 3 is used to support the tray 2, and the turntable 4 is set so that the tray 2 can rotate, which facilitates the installation of bolts at different positions of the electrolytic cell 7.

[0035] In addition, the fastening bolts of the electrolytic cell 7 are located around the perimeter. When applying the tightening force with a wrench, the electrolytic cell 7 needs to be rotated. However, the electrolytic cell 7 is relatively heavy, and rotating and moving it is time-consuming and laborious. There is also a safety risk of it falling and injuring people. Using a turntable 4 to rotate the electrolytic cell 7 can improve efficiency and safety.

[0036] In one embodiment, the positioning rod 5 can slide along the radial direction of the support tray 2.

[0037] In this embodiment, the positioning rods 5 are designed to slide along the radial direction of the support tray 2, so that the distance between the positioning rods 5 can be adjusted to adapt to electrolytic cells 7 of different specifications.

[0038] like Figure 3As shown, in one embodiment, the positioning rod 5 includes a rod body 51 and a slider 52. The slider 52 is disposed at one end of the rod body 51. In this embodiment, the rod body 51 and the slider 52 are detachably connected to facilitate the installation of the slider 52. The support tray 2 is provided with an elongated hole 21. The length direction of the elongated hole 21 is consistent with the radius direction of the support tray 2. A groove 22 is provided on the side of the support tray 2 away from the pad block 6 below the elongated hole 21. The slider 52 is slidably disposed in the groove 22. The rod body 51 passes through the elongated hole 21 and is connected to the slider 52.

[0039] In this embodiment, the width of the slider 52 is greater than the width of the elongated hole 21, and the size of the groove 22 matches the size of the slider 52. With this arrangement, the rod 51 can be perpendicular to the support tray 2 and will not tip over when sliding.

[0040] During installation, first slide the slider 52 into the slide groove 22 from one end, and then let one end of the rod 51 pass through the elongated hole 21 and connect it with the slider in the slide groove 22 through a thread to complete the installation of the positioning rod 5.

[0041] In use, the distance between the positioning holes of the electrolytic cell 7 can be adjusted by pushing and pulling the rod 51 along the direction of the elongated hole 21. At this time, the slider 52 slides synchronously in the groove 22, thus adjusting the distance between the positioning rods 5.

[0042] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
